Positive and negative magnetodielectric effects in A-site ordered (BiMn3)Mn4O12 perovskite.
A-site ordered perovskite (BiMn3)Mn4O12 was synthesized through a high-pressure synthesis route at 5 GPa and found to exhibit two magnetic transitions and to show either a positive or a negative magnetodielectric effect depending on the temperature range/magnetic state.
